Whenever I'm in vimdiff
mode, my PuTTY session slows down considerably. This is especially noticeable when I try to scroll down many lines by keeping j pressed.
- Why is it so slow in comparison to regular Vim running under
vsplit
? I realize it matches across lines and color-highlights the differences, but does that account for all the speed differences? - What can I do about it? I would like to keep line matches across files (and color highlighting as well). What settings can I change to help speed up the performance of my
vimdiff
utility?

Do you have SSH compression enabled? This kind of scrolling and highlighting generates a whole lot of redundant terminal traffic; compression makes a huge difference over a remote link.
